Re: Upgrade of Existinq 36-inches RCP to 66-Inches RCP at Gracewood Drive
Greensboro, NC
To Whom It May Concern:
The City of Greensboro would like to notify your office of the proposed RCP upgrade at
Gracewood Drive by East of Gracewood Court. The project's objective is to upgrade
the existing 36-inch reinforced concrete pipe (RCP) with 66-inch RCP and 55-feet long
energy dissipater. Presently there is an existing 66-inch and 36-inch parallel RCP. The
existing 36-inch pipe is undersized and needed to be upgraded with a 66-inch RCP.
The length of the existing 36-inch pipe is 104 feet and to be replaced by a proposed 66-
inch RCP of 104 feet in length with 25 feet energy dissipater.
Attached is the general information regarding the subject site for your review.
Site: 1514 & 1515 Gracewood Drive at Unnamed Tributary to North
Buffalo Creek along Benjamin Parkway, Greensboro, NC.
Site Condition: Under sized Culvert.
If you have any further questions, please call me at (336) 373-2619
Sincerely,
Ade Idowu

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Existing 36-inch RCP is undersized needs upgrading due to flooding of residents properties.
Based on calculation of the drainage basin there is need for upgrade. The only other option is
DO NOTHING which may create legal action.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USAGE _ In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
Page 11 of 14
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmQide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
N/A
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(919) 733-5208 to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/M/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet):
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
